my compost bin is made of snow fencing, so it is open-air. i turn the pile pretty much daily, and it is never saturated with water. it gets its moisture from small amounts of rain that are allowed to drop in through perforations on the tarp roof, and from the moisture in the grass clippings that i throw in the pile. it has the right earthy smell, etc. i have no reason to believe that the compost yield is going to be anything less than great.
assuming i have sufficient air circulation when brewing and don't let it sit too long before application, is there any reason to suspect it would turn anaerobic or promote the growth of pathogens?
